CyphaspidesDescription: Unusual example of a member of the Order Proetida, Family Aulacopleuridae with many fine details present. It comes from a new location known as Jorf in Morocco, close to the site from which the polished goniatite ammonites originate. The preservation of the exoskeleton is reminiscent of them in terms of texture, unlike many trilobites from Morocco. It has similarities to Cyphaspis (see my other listings) with the same bulbous cranidium, stalked eyes, and granulose appearance. It is a rarely-seen taxon, and most like this one are usually found somewhat disarticulated. The matrix from Jorf is often harder than that from some other sites, making preparation more difficult. The preparation that allowed the cephalon and the fringing spines and most all the dramatic pleurals and genals to be prepared free of matrix took over ONE HUNDRED HOURS, an effort I am sure you will agree was well worth it. With the advent of a reliable source of electricity in Morocco, the quality of preparation has improved dramatically over the past few years. While I used to refer to trilobites prepared in a mode similar to this as flying, I feel a new term is warranted by the preparation now coming into vogue. The rose tint to the trilobite is entirely natural, and adds an aesthetically pleasing touch to the stunning presentation of this unique piece..
